But sorting the data by date does not work at all, it will only sort it by the day which makes sense. I am also grouping the data by the "name" field which works perfectly fine. Option 1 - branched if statement: if (order.side = "buy") ,īut in my mounted hook I'm overriding the date field to format it as requested by the product owner. Conversely, my understanding so far of an alternate solution is that multiple template function overloads could be used to decide which function is called, where the chosen function is the one whose template arguments/requirements are best matched or fully satisfied by the incoming type/class.

One way to deal with that would be a simple if-else statement that checks if it's a buy order and runs the corresponding function to process a buy order message.

There is even a patch where the quartz trace shows the strata to have. Let's say a new message arrives from the exchange and it's a "buy" order. It makes a sound like distant cannon fire, an irregular salvo fired in an orogenic. The application I'm thinking about is for automated trading. What I can't seem to find an answer for is, does that remain branchless at runtime and/or is the act of finding which function to call based on the overload/specialisation cases faster than an if-else block? What I'm trying to understand is - techniques like template metaprogramming and SFINAE/concepts in C++20 can both compute and remove branches at compile-time.

May I know what is the problem of my code and how can I fix this? #includeĪpologies if any of the terminology is wrong here. For instance, when I choose option '1', it will succeed but as I input again at next try like option '2', it is still going to option '1' even in password(). It works fine when I execute the first loop but when I have to go back to the menu() and also password(), whatever I type is always the first value of first loop. I'm not a good coder so, I know my code is not that good. *** stack smashing detected ***: terminated Aborted (core dumped) What I want is to know what's wrong with my code, I know quicksort may be done in a better way, So please If someone can point out the problem with my code It'll be a big help. I may have made some bad mistakes so don't mind if the problem is silly. I would have liked to give more references and articles in english about this flaw but nobody seemed have write about this thing. _fortify_fail_abort is added to avoid backtrace from _libc_message is changed to acceptĮnum _libc_message_action and call BEFORE_ABORT only if action includesĭo_backtrace. _stack_chk_fail is called on corrupted stack.

That is why, sometime last year, some developers decided to avoid to use argv when displaying information about the stack-smashing and replaced it by. If a secret key or some confidential data were stored in the stack, then an attacker can access it through this feature. As fork() is cloning the memory of the initial process, the ASLR was useless because the same starting memory image was used and, then, the same memory mapping was used again and again. This technique was mainly used in servers where fork() was used to respawn an instance. Indeed, if you can control the address at argv and crash the application, you can leak the whole stack outside of the application. But, some attackers started to exploit the fact that you could overflow the stack, reach the argv and overwrite it with an address that you choose. The " " (which is a static string added by -fstack-protector) that you see was previously argv. In fact, this is a fairly recent mitigation mechanism introduced to avoid to leak information about the stack of the crashed application.
